PORT ST. LUCIE — Jason Vargas walked through the Mets clubhouse Sunday morning with a wrap on his right hand that could have doubled as a weapon.

Now the big question is whether he will begin the season ready to pitch.

The Mets left-hander has been diagnosed with a non-displaced fracture of his glove hand, after getting drilled with a line drive on Friday in a minor league exhibition game. Vargas is expected to meet with a hand specialist Sunday to discuss his options.

Among those options, according to general manager Sandy Alderson, is surgery that would sideline Vargas for an undefined period.

“He will either pitch through it or have it surgically repaired,” Alderson said. “And the question is if he pitches through it, what effect that will have on his preparation and secondarily, if he has the surgery, what impact that has, and I can’t really answer either of those questions right now.”

If Vargas is sidelined, the beneficiary likely would be Zack Wheeler, who has battled Steven Matz this spring for the final spot in the Mets rotation. The job is Matz’s to lose heading into the final week of the Grapefruit League season, according to sources, based on the left-hander’s solid performances in his last two exhibition appearances after a slow start to the spring.

Wheeler was strong earlier in the spring, but fizzled against the Nationals in his last start. Both Matz and Wheeler are scheduled to pitch Monday — the latter will participate in a minor league game.

Vargas signed a two-year contract with the Mets worth $16 million to provide the team with rotation depth after injuries depleted the pitching staff last season.
